Apple clang version 14.0.0 (clang-1400.0.17.3.1) fails the build
because stds.h defines `fallthrough` as a macro which is then
expanded when base.h evaluates
# if __has_attribute(fallthrough) && __clang_major__ >= 5
The macOS SDK defines `DISPATCH_FALLTHROUGH` as the macro instead
of `fallthrough`.
This change replaces the use of `fallthrough` in the tree with
`HEIM_FALLTHROUGH` and updates the declaration in configure logic
to define `HEIM_FALLTHROUGH` based upon existing definitions
(if any) of `fallthrough` or `DISPATCH_FALLTHROUGH`.
The pseudo keyword 'fallthrough' is defined such that case statement
blocks must end with any of these keywords:
* break;
* fallthrough;
* continue;
* goto <label>;
* return [expression];
*
* gcc: https://gcc.gnu.org/onlinedocs/gcc/Statement-Attributes.html#Statement-Attributes
The macro is defined either as
__attribute__((__fallthrough__))
or as
do {} while (0) /* fallthrough */
not including the semicolon.
This change implements the Linux kernel style and updates several locations
where "/*fallthrough*/ and /* FALLTHROUGH */ were not previously replaced.
Externally imported code such as libedit, libtommath and sqlite are
restored to their unaltered state.

Setting `dns_lookup_realm = false` in `[libdefaults]` and setting name
canon rules that force the empty realm causes destination-TGT delegation
to break because the client doesn't know the service's realm.
Because MIT and Heimdal check that the (unauthenticated plaintext)
sname/realm of the Ticket in the KDC reply matches the sname/srealm in
the enc-part of the KDC reply, we know we can trust the realm of the
ticket found in the ccache. So use that.
Refactor and enhance TGT forwarding to allow forwarding of leaf
(destination) TGTs for selected destination realms.
Enhance kinit(1) to renew non-origin realm tickets
Document delegate-destination-tgt
Use the newly implemented _krb5_mk_1cred().
most of these warnings are not problems because of ample
use of abort() calls. However, the large number of warnings
makes it difficult to identify real problems. Initialize
the variables to shut up the compilers.

The clock skew handling was previously only on properly wrapped
GSSAPI, and was skipped for DCE-style. This allows the ASN.1 errors
from the krb5_rd_req to suggest parsing as a kerberos error packet.

This makes it much more clear that the timestamp written here is not
used in mutual authentication.

The the realm of the user's principal and prefer that when doing a lookup.
This code still need to be smarter can cache the "initial value" -> positive result
to avoid roundtrips to the KDC.
